Kromattava

Kromattava is a Finnish term used in metal finishing to describe a surface or substrate that is suitable for chromium plating. It is the participial form of the verb kromata, meaning to chrome, and translates roughly to “chromable.” In industrial practice, the word indicates materials prepared to receive a chromium layer through electroplating or chemical deposition.

The concept is applied across automotive, hardware, and tooling industries, where a chrome finish combines appearance, corrosion resistance, and, in some cases, hardness. A kromattava surface can be steel parts, certain aluminum alloys with appropriate pretreatment, or previously plated layers that permit chromium deposition. The specific preparation depends on the substrate and the intended chromium class.

Chromium plating used on kromattava surfaces is generally categorized into decorative chrome and hard chrome. Decorative chrome aims for a bright, smooth appearance and moderate wear resistance, while hard chrome provides greater hardness and durability for functional components. Surface preparation typically includes thorough cleaning and degreasing, descaling or pickling for steel, and an activation or strike step to promote chromium deposition. Chrome is deposited from a chromium-containing electrolyte, and some substrates may require intermediate layers such as copper or nickel.

Environmental and safety considerations accompany kromattava operations. Chrome plating has historically involved hexavalent chromium, a toxic, highly regulated substance, prompting tighter controls and a shift toward trivalent chromium processes and alternative coatings in many regions. Waste treatment, emissions control, and compliance with local environmental regulations are essential aspects of kromattava practice.

In summary, kromattava denotes the suitability of a surface for chromium plating, encompassing preparation, deposition, and compliance aspects common to chrome finishing.
